Abstract

The utility model discloses a wide angle LED lamp structure which mainly comprises a lamp holder and a substrate arranged on the lamp holder; the substrate is provided with a first carrier surface and a second carrier surface surrounding the first carrier surface, and at least a LED is respectively arranged on the first and second carrier surfaces; an included angle Theta formed between the first and the second carrier surfaces is in the range of 5 degrees to 30 degrees, and the substrate is slightly convex. When the LED on the substrate illuminates, as the included angle Theta is formed between the first carrier surface and the second carrier surface, the LED on the first carrier surface mainly irradiates upwards and the LED on the second inclined carrier surface irradiates all around, the light coverage angle is enlarged, and the lighting efficiency of the LEDs is sufficiently utilized.

Description

The wide-angle LED lamp structure

Technical field

The utility model relates to a kind of LED lamp structure, particularly a kind of angle that changes the base plate carrying light emitting diode, and the tool of arranging in pairs or groups again expands the lampshade of photo structure, the wide-angle LED lamp structure that the light emitting diode range of exposures is more strengthened.

Background technology

In the design of general existing LED bulb, how LED directly is located on the substrate on plane, and be smooth storing, and existing substrate has except electrically connecting with LED, also has the function that is connected with cooling mechanism and helps to dispel the heat.

Though the substrate structure on plane is simple, be convenient to be provided with and put LED, but its tabular surface has limited to the luminous position of LED on substrate, only make LED comply with its set position and angle, cooperate the expansion light modulation cover of outer cover that light is spread slightly, and the luminous scattering angle of existing general LED bulb does not only wait at 120 °～180 °, though there is the expansion light modulation cover of outer cover to help the light diffusion, but effect is very little, and it is not enough that the light diffusion is still disliked; In addition, the substrate on existing plane, the conjugation of its tabular surface and cooling mechanism is often not satisfactory, so that heat conduction and radiating effect are also limited.The creator satisfies the spy and creates into this case to grind in view of known disappearance, and the proposition of phase energy mat this case has shortcoming now in order to do improving, and the phase can attain this kind product and causes perfect, desirable and practicality.

The utility model content

Main purpose of the present utility model is to provide a kind of improvement to have LED lamp structure now, makes the light emitting diode illumination range wider, and has the LED lamp structure that promotes additional functions such as heat radiation concurrently.

For reaching above-mentioned purpose, the concrete technological means of the utility model is:

Described wide-angle LED lamp structure comprises: a lamp socket; One is located at the substrate on the lamp socket, and substrate has one first section and around first section, second section on every side, first section and second section are provided with at least one light emitting diode; Constituting one between first section and second section makes substrate slightly be convex between 5 °～30 ° angle theta.

By above-mentioned technological means, the attainable effect concrete manifestation of the utility model is: when making the lumination of light emitting diode on the substrate when the utility model electric connection, because tool angle theta between first section and second section, so except irradiation upwards is light emitting diode on main first section, be the light of the light emitting diode on skewed second section can be more towards around irradiation, the angle of light expansion is wider.

The specific embodiment

Those skilled in the art below cooperate Figure of description that embodiment of the present utility model is done more detailed description, so that can implement after studying this specification carefully according to this.

Head sees also Fig. 1 to shown in Figure 4, and wide-angle LED lamp structure of the present utility model comprises:

One lamp socket 1.

The lampshade 2 of one cover cap lamp socket, 1 upper end, polygonal solid array 21 is laid on lampshade 2 surface, and polygonal solid array 21 refrangible light more spread light in the lampshade 2 and evenly.

One is located at the radiating subassembly 3 in the lamp socket 1.

One is located at the substrate 4 on the lamp socket, and substrate 4 has one first section 41 and second section, 42, the first sections 41 and second section 42 around first section 41 are provided with at least one light emitting diode 5; Constituting one between first section 41 and second section 42 makes substrate 4 slightly be convex between 5 °～30 ° angle theta, angle theta can make the irradiating angle of light emitting diode 5 on substrate 4 extend into 210 ° (extremely shown in Figure 6 as Fig. 5), and existing irradiating angle enlarges more; The optimum range of angle theta is 8 °～15 °, and this scope not only illumination range is vast, and light efficiency is also splendid; The periphery of substrate 4 is offered at least one fluting 40, and the 40 formed intervals of slotting help the bending process of second section 42 of substrate 4, makes substrate 4 bendings more easy.

In addition, substrate 4 with angle theta, radiating subassembly 3 contact-making surfaces in itself and the lamp socket 1 are more, and first section 41 and second section, 42 formed area of dissipations also the substrate of existing whole plane is bigger, so the additional function that its auxiliary heat dissipation assembly 3 dispels the heat is also better.

When the utility model electrically connects and when making light emitting diode 5 on the substrate 4 luminous, because tool angle theta between first section 41 and this second section 42, so except irradiation upwards is light emitting diode 5 on main first section 41, be the light of the light emitting diode 5 on skewed second section 42 can be more towards around irradiation, it is wider that irradiation is contained, and the angle of light expansion is bigger; Again, when the light of light emitting diode 5 passes the polygonal solid array 21 of lampshade 2, the three-dimensional knuckle of polygonal solid array 21 can produce the effect of refraction to the light that passes, the light range of exposures that has strengthened is more strengthened again, then make light through lampshade 2 refractions more evenly soft and do not stimulate eyes on the other hand.

The above only is in order to explain preferred embodiment of the present utility model; be not that attempt is done any pro forma restriction to the utility model according to this; therefore; all have in that identical creation spirit is following do relevant any modification of the present utility model or change, all must be included in the category of the utility model intention protection.
