Detailed ways

Embodiment one

It can be seen from Fig. 1 (the upper part is cut away), an LED light source module provided in this specific embodiment includes: a lamp holder 1, a radiator assembly 2, a light source assembly 3, a reflector cup 4, a floodlight cover 5 and a structural member 6 .

One end of the lamp holder 1 includes a power interface 11, and the power interface 11 can be a common screw socket, bayonet socket or socket on a general light bulb (sockets are generally used for spotlights). The electrodes on the power interface 11 are used to contact and electrically connect with an external power source, and the electrodes are also electrically connected to the light source assembly 3 through the power line 12 .

The light source assembly 3 includes a substrate 32 and an LED chip 31 disposed on the substrate 32 . There can be one or more LED chips 31, which are selected and arranged according to needs.

The reflective cup 4 covers around the light source assembly 3 , specifically around the LED chip 31 . The floodlight cover 5 is covered at the opening of the reflector cup 4 . The reflective cup 4 reflects and gathers a part of the light around the LED chip 31 , and finally the light emitted by the LED chip 31 is transmitted through the flood cover 5 as much as possible, thereby improving the lighting efficiency and the illuminance. The floodlight cover 5 is fixed on one end surface of the radiator assembly 2 through the structural member 6, and the light passing through the floodlight cover 5 will become softer instead of dazzling. In addition, in addition to the function of fixing the floodlight 5, the structural member 6 can at least play a decorative role as required.

The structure of the radiator assembly 2 is the key point of the present invention. It can be seen from FIG. 1 that the radiator assembly 2 of this specific embodiment includes: a bottom plate 21 , a radiator main body 22 and cooling fins 23 . Wherein, the hollow cylindrical radiator main body 22 and the cooling fins 23 are integrated; both are integrally processed by cutting a hollow profile; the processing of the profile belongs to the existing mature technology, and will not be described in this article. The bottom plate 21 is formed by punching or cutting sheet materials; the bottom plate 21 and the radiator main body 22 are fixedly connected by an interference fit, and one end of the radiator main body 22 is closed, so the processing cost of the entire radiator assembly is low. Moreover, since the bottom plate 21 is processed separately, the light source assembly 3 can be installed before the bottom plate 21 is assembled, so the assembly is more convenient. The fixed connection method of interference fit makes reliable contact between the bottom plate 21 and the radiator main body 22, which is conducive to the smooth conduction of heat from the bottom plate 21 to the radiator main body 22; and the connection method of interference fit has the simplest structure and is easy to assemble. More convenient.

In addition, for better positioning between the bottom plate 21 and the radiator main body 22 , a positioning step 221 is provided at the opening of the end of the radiator main body 22 for fixing the bottom plate 21 .

The heat dissipation fins 23 have multiple pieces, which are evenly distributed on the outer wall around the radiator main body 22. The heat dissipation fins 23 can be planar, spiral, or other common shapes as required.

Further, the outer outline of the radiator assembly 2 (actually the outer outline formed by a plurality of cooling fins 23 ) can be smoothly transitioned with the outer outline of the lamp holder 1 , which is more beautiful and safe and convenient to use.

One side of the substrate 32 is in close contact with the bottom plate 21 to ensure that the heat generated by the LED chip 31 can be smoothly transferred to the bottom plate 21 . In order to conduct heat more smoothly, a thermally conductive adhesive layer can be placed between the substrate 32 and the bottom plate 21 .

Furthermore, a plurality of anti-slip pins 13 can also be arranged around the periphery of the lamp holder 1, so that even if the lamp holder is held on the smooth lamp holder 1 during installation, it is not easy to slip.

As can be seen from FIG. 1 , a wire hole 211 is provided on the base plate 21 for the wire 12 connecting the power interface 11 and the base board 32 to pass through.

Embodiment two

An LED bulb lamp provided in this specific embodiment, as shown in FIG. 2 , differs from the first embodiment mainly in that a bulb cover 7 is provided on the periphery of the floodlight cover 5 . The bulb 7 is relatively large and has a floodlight effect, which can make the light softer. According to needs, the bulb cover 7 can be selected in various colors, so that the LED bulb lamp can emit light of the selected color and become an LED illusion bulb lamp. LED magic color bulbs are gradually replacing traditional bulbs due to their advantages of low power consumption, long life (average lifespan up to 90,000 hours), changeable colors, and synchronous and coordinated control, and can be widely used in interior lighting of glass curtain walls. Transparent effects, signboard advertisements, rainbow doors, home decoration, stages, shopping malls, entertainment venues, etc.

Embodiment Three

An LED spotlight provided in this specific embodiment, as shown in FIG. 3 , differs from the first embodiment mainly in that a reflector 8 is provided around the flood cover 5 . The reflector 8 is generally bowl-shaped, which can converge the light transmitted from the flood cover 5 to a certain extent, so that the illumination of the illuminated area is higher. Traditional spotlights mostly use halogen lamps, which have low luminous efficiency, relatively high power consumption, rising ambient temperature and short service life. LED spotlights are far superior to traditional lighting products in terms of luminous principle, energy saving, and environmental protection, and the unidirectionality of LED light emission forms a perfect support for the light distribution of spotlights. In addition, for the LED spotlight in this specific embodiment, the power interface 11 adopts a common socket for spotlights, which is convenient for installation and replacement.

Embodiment Four

Downlight is a directional lighting fixture, only its opposite side can receive light, the beam angle belongs to spotlight, the light is more concentrated, the contrast between light and dark is strong, it can highlight the illuminated object, the lumen is higher, and it can bring out a quiet environment atmosphere. It is often embedded in the ceiling, so it can maintain the overall unity and perfection of architectural decoration. Because the light source is hidden inside the building decoration, the light source is not exposed, no glare, and the visual effect is soft and uniform, so it is often used in high-end interior decoration. An LED downlight provided in this specific embodiment, as shown in FIG. It is obviously darker, so it can make the irradiation angle smaller and achieve the effect of directional lighting; at the same time, it also makes the light more concentrated and the illuminance is higher. Compared with traditional downlights, the LED downlights in this embodiment are green and environmentally friendly products, more energy-saving, and have a service life of 10,000-50,000 hours, which is almost 10-50 times that of ordinary halogen spotlights.

Of course, generally speaking, the reflective cup 9 also includes a cup cover 91 covering its periphery, and the cup cover 91 is used to fix the reflective cup 9 and protect the reflective cup 9 . In addition, the cup cover 91 can also be printed with various patterns as required, and various patterns and external shapes can be processed to play a decorative role. In addition, in the LED downlight of this specific embodiment, the power supply interface 11 adopts a bayonet socket, and the lamp cap 1 is not provided with an anti-slip pin 13 .
