New description: [New technical field] The present invention relates to a kind of lighting device, in particular to a lamp with LED as a light source. [Prior Art] Since the development of LED (light-emitting reduction), from the early days of hiding electronic display light sources, to the recent use of traffic numbers, automobile taillights and lighting fixtures, the range of use of f has gradually become popular. 1^ has low power but luminous efficiency. iQ's the advantages of power saving and longevity, which led to the development of lighting fixtures, which can gradually replace traditional incandescent, neon, south and arc lamps. LED lamps that have been developed today include bulbs, recessed lamps and lamps. Among them, LED tubes have been replaced by fluorescent lamps for illumination by some agencies or factories, in order to save power consumption. Although these lamps have the advantages of lower power saving and longer life than the conventional camping lamps, the LED lamps have the disadvantage that the LEDs in the lamp holders are disposed on the surface of the circuit board, and only one row is arranged in the current lED lamp. The downward illumination of the LED, the best range of illumination only includes the lighter's direct opening angle, and the surrounding area is dim, so the illumination of the LED tube is not as good as that of the traditional fluorescent lamp. In addition, most of the current LED lamp covers are made of glass or PC. The lampshades of these materials can only allow light to pass through and cannot adjust the light type of the emitted light to meet the needs of special lighting. [New content] In order to solve the problem of the illumination range of the known LED tube, the present invention thus provides an LED lamp which can expand the illumination range of the LED tube. The LED lamp provided by the novel model can also adjust the light type of the illumination light for the use requirement. 3 ^1516 The LED lamp of the present invention has the same heat dissipation portion as the known LED lamp tube, and at least one circuit board is disposed on at least one surface of the heat dissipation portion. The circuit board is provided with a plurality of LEDs, at least one cover. The body covers the outer side of the combination of the heat dissipating portion, the circuit board and the plurality of LEDs, and the Ted 1 of the present invention has a heat dissipating portion having a top surface and a bottom surface opposite to the top surface, and a top surface and a bottom surface form a Hollow spacing; circuit boards are respectively disposed on the surface and the bottom surface of the heat dissipating portion; the plurality of LEDs are respectively disposed on the top surface and the bottom surface of the heat dissipating portion; and the outer surfaces of the top surface and the bottom surface of the heat dissipating portion are respectively covered.

The LED lamp of the present invention has the above-mentioned structure, and the plurality of LEDs respectively disposed on the heat-dissipating surface circuit board can emit light from the skin directly and directly from the skin, and the LED lamp tube is known. Such as It: Light has a large illumination range. The new 2LED lamp of the present invention, which is covered by the side of the top surface of the heat dissipating portion, can adjust the light type of the emitted light, ^ « for example using a convex lens The cover body can make the emitted light have a concentrating effect, so that the β concave lens cover can make the emitted light have a diverging effect, and therefore, it can be Μ 4* at m for the known type of light that cannot be changed by the LED tube. The need for the use of the light, the preferred cover of the cover is covered by the top of the top portion of the heat dissipating portion and combined with the heat dissipating portion. The LED lamp from the library B is in which the preferred cover covers the outer surface of the heat dissipating portion and the bottom surface of the heat dissipating portion and is combined with the plurality of LEDs. The light-emitting portion of the top surface and the bottom surface of the preferred heat-dissipating portion of the LED illuminator can be respectively formed to cover the light-emitting portion; the outer side of the light-reflecting portion is preferably combined with the second cover; the cover is preferably It is one of the convex lens cover or the M411516 four-mirror cover. In order to make the understanding and understanding of the purpose, shape, structure and function of the new type of the present invention, the embodiment and the figure are described in detail as follows: [Embodiment] See the ® 'The LED lamp i of the preferred embodiment of the present invention, the heat-dissipating portion 1G having a top (four) and a bottom surface 12 with respect to the top surface, a hollow space 13 formed between the negative and the bottom surface; - a circuit board 20, respectively disposed on the top surface u and the bottom surface 12 of the heat dissipation portion 1G; on the outer surface of the circuit board 2 () is provided with a plurality of LEDs 30; and the top surface n and the bottom surface 12 of the heat dissipation portion 1 The outer side is covered with an adjustable light-type cover 40, respectively. An LED lamp cartridge according to the first preferred embodiment of the present invention, wherein the heat dissipating portion 10 is an extruded body, and the top surface 丨丨 and the outer surface a of the bottom surface 12 have grooves 111 and 121. The opening side of the cover 4 is provided with a convex rail 41 which can be engaged with the grooves 111 and 121. The combination of the grooves m, 121 and the convex rail 41 enables the cover 40 to cover the heat dissipation portion. The top surface of the 10 and the outer side of the bottom surface are combined with the heat radiating portion. In addition, the hollow Φ 13 between the top and bottom surfaces of the heat dissipating portion 1 can not only dissipate the heat collected by the LEDs 30 on the top and bottom surfaces, but also increase the heat dissipating area of the heat dissipating portion, so that the lamp of the present invention Led can play a more efficient work and extend its service life. As shown in the figure, the LED lamp 1 of the first preferred embodiment of the present invention, wherein the light-receiving cover 40 is used, means that the light emitted by the LED 30 can change direction after passing through the cover. To achieve this function, the lamp body 1 of the first embodiment of the present invention has a cover body 40 which is a cover body of a concave lens, that is, a cover body having a thinner central portion and gradually thicker toward the both ends of the convex rail 41. The cover body can produce the effect of a concave lens, and the light emitted by the LED 30 can pass through the cover 40 after passing through the cover 40, thereby generating an astigmatism effect which is more outwardly diffused (such as the direction of the arrow in the figure), so that the cover 40 is installed. The use of the same (four) 3 〇 〇: produces a wider range of illumination than the general hood; for example, the second figure is the use of a concave lens cover of the present invention - the preferred embodiment (four) coffee luminaire The light intensity of the LED lamp is measured (4), wherein the lamp having the thickness of the cover has a light intensity of a curve 51 and a full angle of about 110 degrees; and the coffee lamp of the novel preferred embodiment using the concave lens cover i , its light intensity is curve 52, * angle is about 145 degrees The full-angle of the full-width cut-off equal-thickness cover of the LED lamp i of the first preferred embodiment of the present invention can be seen that the LED lamp i of the first preferred embodiment of the present invention can emit more light to both sides of the LED 30. And to enhance the range of illumination of LED lights. As shown in the first figure, the LED lamp of the first preferred embodiment of the present invention uses a lamp cover 4 with a concave lens of the light divergence principle to increase the full angle of the light emitted by the lamp, thereby improving the illumination range of the lamp. In the same principle, the convex lens having the principle of light convergence can also be formed into a lampshade, so that the full-angle angle of the emitted light of the lamp using the lampshade becomes smaller, and the scattered light generated by the original concave lens is concentrated in the middle to form a poly The effect of light, such as the LED lamp 2 of the second preferred embodiment of the present invention shown in the third figure, except that the cover 40a is the same as the lEd lamp 1 of the first preferred embodiment, the cover 40a thereof The thickness of the cover is thicker in the center and is thinner toward the two ends of the convex rails 4la. The cover of this type can produce the effect of a convex lens, and the light emitted by the LED 30 can pass through the cover 4〇a to generate an outward direction. Convergence (such as the direction of the arrow in the third figure). In the LED lamp 1 of the first and second preferred embodiments of the present invention, the cover bodies 40 and 4〇a are all coupled to the heat dissipating portion 1〇, and the other possible manners can also cover the cover body M411516 & The LED lamp 3 of the third preferred embodiment of the present invention has a structure in which the bottom end of the cover 4b has a hook 41b, and the side of the LED 30b forms a recess into which the hook 41b can be inserted. The groove 3lb can be easily attached to the outside of the lamp by the recess 31b on the side of the LED 30b by the hook 41b of the cover 40b. The LED lamps 丨, 2 and 3 of the first to third preferred embodiments of the present invention are provided with adjustable light-shielding covers 4〇, 4〇a and 40b; however, other feasible ways to adjust the function of the light type It can be achieved by other structures, such as the LED lamp 4 of the fourth preferred embodiment shown in FIG. 5, wherein the heat dissipating portion 60 is an extruded body having a top surface 61 and a bottom surface 62 opposite to the top surface. A hollow space 63 is formed between the surface and the bottom surface; the circuit board 2〇c is respectively disposed on the top surface 61 and the bottom surface 62 of the heat dissipation portion 60; and the plurality of LEDs 30c are disposed on the outer surface of the circuit board 2〇c. The lED lamp 4 of the fourth preferred embodiment is different from the above-described preferred embodiments in that the top surface 61 and the bottom surface 62 of the heat dissipating portion 6 are respectively extended outward to form an arc-shaped light reflecting portion 64, 65. By changing the curvature of the light reflecting portions 64, 65 and the flatness of the surface thereof, for example, surface plating treatment, the light reflecting portions 64, 65 can replace the cover and have a function of adjusting the direction in which the LED emits light. .
